Definitions
- the present invention relates to the loading of sheets of paper in office machines such as printers, fax machines, photocopiers, comprising two magazines and two withdrawal devices for two bundles of sheets of paper.
- a fax machine If you consider for example a fax machine, it has a printer fed with blank sheets of paper by a feeder and a scanner associated with another sheet feeder to be analyzed.
- each charger comprises one or more drive rollers with a device for removing a sheet of the bundle.
- the present invention aims to provide an office machine with very simple constitution sheet feeder, allowing a feeding selective from two stores.
- the invention relates to an office machine comprising a sheet feeder with two paper trays storage of sheets, respectively for two separate organs of the machine, and means for picking up sheets from each store, comprising at least one pick-up roller mounted on a shaft, with means for driving the rotating shaft, characterized in that the means for driving the rotating shaft are arranged to drive it in both directions, the tree is common to the means of removal of the two stores and the shaft carries at least two freewheeling pick-up rollers integral in rotation with the shaft respectively in two opposite directions.
- the loader of the machine of the invention which allows selective leaf feeding from two stores, does not include a single sampling device but two devices combined one with the other, with a pick roller drive shaft which is common.
- the whole is more compact and less complex, while preserving the functional characteristics of the two sampling devices.
- a first of the stores has a partition in which is provided a window out of which protrudes the roller associated sample, the partition of the first store is shaped to wrap pebbles associated with the second store and arranged on either side of the pick-up roller associated with the first magazine and the pick rollers of said second magazine are mounted at the right of two windows, made in the partition of the first store in which they are engaged without protruding from it.
- FIG. 1 there is shown here the charger of a fax.
- a bundle of document sheets 4 to be analyzed optically in the fax scanner is stored in a first store 3 and a bundle of blank sheets to print 2 is stored in a second store 1.
- the first magazine 3 has a partition 13 which branches out into a skirt 31 forming a partition of the second store 1.
- the sheets 2 and 4 are guided by the skirt 31 and by the partition 13, respectively.
- sheets 2 and 4 are maintained slightly tilted vertically, in the functional position shown and their front edges abut against a cornered delinking member 11 and against a spreader with spreader beam 12, respectively.
- the sheets will be taken from the two stores by pebbles mounted on a sampling shaft 9, which can be rotated in both directions, by a motor not shown.
- Tree 9 is common to both stores. Here it carries a central pick-up roller 10, for the first magazine 3 and, on either side of the roller 10, two pick-up rollers 7, 8 for the second store 1.
- the three rollers are thus coaxial.
- the diameter outside of the rollers 7, 8 is slightly higher than that of the central roller 10, for a reason that will appear quickly below.
- the three rollers 7, 8, 10 are freewheel rollers mounted integral in rotation with the shaft 9, in direction B anticlockwise, in Figure 1, for the central roller 10 of the first magazine 3, clockwise A, for the rollers side 7, 8 of the second magazine 1.
- the partition 13 of the first store 3 is shaped to wrap the pick roller 10 of the first magazine 3 and the pick rollers 7, 8 of the second magazine 1.
- the partition 13 is curved at the level of the shaft 9 and of the three rollers, according to a quasi-cylindrical surface, but of larger diameter at the two outer rollers 7, 8 of the second store 1.
- a first window 221 is formed in the partition 13, outside of which protrudes the roller 10 to drive the sheets 4.
- the rollers 7, 8 of the second store 1 are mounted to the right of two windows 70, 80 formed in the partition 13 of the first store 3, windows in which they are engaged but not protruding, due to the more pronounced bulging of the partition 13 in these places and despite their diameter larger than that of roller 10.
- the first magazine 3 has a spreader system with spreader bars 12.
- the second store 1 comprises a pallet 5 mounted to rotate under the action of a return spring 6, to push the sheets 2 against the pick rollers 7, 8.
- the sheets 2 are guided by the skirt 31 to pass from one side of the sampling shaft 9, on the right in FIG. 1.
- the partition 13 guides the sheets 4 to abut against a shoe shredder 17 of the shredder system 12 shaped around the periphery of the roller 10 associated with a lifter 15 of the shredder 12 which is put under pressure by a spring 16.
- FIG 3 which is a median radial section, shows in detail the shredder device 12 cooperating with the partition 13 and the roller 10, one of which periphery portion is accessible to the sheets 4, deformed radially and flattened above by the delineator pad 17 and the lifter 15.
- FIG. 4 which is a radial section at the level of the roller 8, illustrates the fact that the rollers 7, 8 are not accessible to the sheets 4, of the side of the shaft 9 where the partition 13 extends.
- the windows 70, 80 are intended to avoid any risk of friction of the rollers 7, 8 on the internal side of the partition 13.
- the diameter of the roller 10 is less than that of the rollers 7, 8 for prevent this roller 10 from cooperating with the sheets 2 of the second magazine 1.
